1. "And Hashem spoke to Moses, saying: 'This shall be the Torah of the leper in the day of his cleansing'" (Vayikra 14:1-2). Rabbi Aba opened the discussion with the verse: "Be afraid of the sword: for wrath brings the punishments of the sword that you may know that there is judgment (Heb. shadun)" (Iyov 19:29). It is PRONOUNCED, "shadun," but spelled shedin (lit. 'demons'). Observe in how many ways people should guard their way, fear the Holy One, blessed be He, and not depart from the right way, and people should neither transgress the laws of the Torah nor ever leave her.
2. He who does not learn the Torah and does not strive by her is scorned by the Holy One, blessed be He. The Shechinah does not rest upon him and the guardian ANGELS who accompany him TO PROTECT HIM depart from him. Moreover they stand before him proclaiming: 'Withdraw from this man, for he does not honor his Master.' Woe to him, for he is abandoned by the upper and lower beings and has no part in the way of the living.
3. When man makes an effort in serving his Master and learns the Torah, many guards are there to protect him. The Shechinah also rests upon him and everyone proclaims: 'Honor the image of the King! Honor the son of the King! He is protected in this world and the World to Come! Blessed be he!'
4. Come and behold: the evil tongue of the Serpent, with which he spoke to the woman, brought death upon the man, the woman, and the whole world. Thus, it is written: "And their tongue a sharp sword" (Tehilim 57:5), referring to the evil tongue. Therefore, "be afraid of the sword," NAMELY the evil tongue. What does the following verse mean? "For wrath brings the punishments of the sword." This is "the sword of Hashem," for as we learned, the Holy One, blessed be He, has a sword with which He punishes the wicked, as it is written: "the sword of Hashem is filled with blood" (Yeshayah 34:6). It is also written: "My sword shall devour flesh," (Devarim 32:42) FOR THIS IS THE ASPECT OF JUDGMENT WITHIN MALCHUT. Therefore, "be afraid of the sword for wrath brings the punishments of the sword that you may know that there is judgment," WHICH MEANS that you know it has been so decreed, and THAT ANYONE who has a sword in his tongue - NAMELY, HE WHO SPEAKS WITH THE EVIL TONGUE - is punished with the sword that destroys all, FOR THIS IS MALCHUT FROM THE SIDE OF JUDGMENT. This is the meaning of: "This shall be the Torah of the leper;" THAT IS, MALCHUT FROM THE ASPECT OF JUDGMENT, WHICH IS CALLED 'THIS,' JUDGES THE LEPER FOR HIS EVIL TONGUE, BECAUSE PLAGUES COME FROM THE EVIL TONGUE.
5. Rabbi Elazar cited the verse: "Like the birds that are caught in the snare, so are the sons of men snared in an evil time" (Kohelet 9:12). Although we have already learned this verse, come and behold: people are not aware of their Master's desire and do not listen to it, nor do they look to it. The supernal announcer goes before them every day to awaken them, but no one is there to listen to him and no one awakens his spirit to worship his Master.
